To what volume must a solution of 83.1 g H2SO4 in 505.3 mL of solution be diluted to give a 0.28 M solution?

Question

I do not understand this problem. Also as a hint the professor said to use M1V1= M2V2.

Answer 1

Figure the moles in the H2SO4

moles= mass/molmassH2SO4

That is Molarity1

M1*V1=M2*V2

solve for V2

Answer 2

Figure the moles in the H2SO4

moles= mass/molmassH2SO4

That is Molarity1

M1*V1=M2*V2=molesabove

solve for V2
